Make-Up Circuit
One circuit of the integral boost pump is used as a make-up
circuit to cover leakage
in .the main circuit. The boost
pump draws oil from the tank and supplies it through filter (7)
with bypass valve via the appropriate make-up check valve (8) to
the low pressure side, which is always connected - by means of
the high pressure operated change over valve(4.1) - with the
flushing valve (4.2). With the pump in the centre position, the
make-up oil is directed to the check valve (9) and via flushing
valve (4.2).

Control oil supply
When the HO control (3) is fitted, the second auxiliary pump serves as a force intensifier and pilot circuit. Flow and operating
pressure range are designed to suit the requirements for short
swivel times.
The swivel time of the pump can be controlled by means of a
throttle valve (6) fitted in the pipework. The control pressure is set at the required value by means of a built-on force intensifier valve (5).
The pilot oil is taken from the control
fice (10). (Pilot oil flow approx. 4 Umin).
